The room was evacuated during a briefing with White House spokesman Josh Earnest.

The evacuation was limited to the White House Press Briefing Room and did not affect any other sections of the White House.

A Secret Service sniffer dog was deployed to check out the area.

After being evacuated, reporters headed to what is known as Pebble Beach where the television networks have their live positions, then were moved to the South Court Auditorium in the nearby Eisenhower Executive Office Building. Press held there for about 25 minutes before given the all clear to return to the briefing.

The briefing with Earnest resumed around 2:45 p.m. He attempted to get back to the cybersecurity question he was in the middle of answering prior to the evacuation but instead, was greeted by a volley of questions.

The president and the first family were not evacuated, Earnest told reporters, adding Obama was on the White House grounds at the time.
